  • PROFESSIONAL GUITAR STRINGS: Discover your guitars true voice! Martin Authentic Acoustic strings are designed with higher tensile strength and tin-plated core wire to enable a full and balanced tone, a quicker response, and an increased tuning stability.
  • HIGH-QUALITY DESIGN: Made from 80/20 bronze, this set of 6 strings features top-quality bronzed-steel core wire and bronze wrap wire. At first, the sound is a bright, punchy attack. It quickly mellows out as you play, making this pack ideal for bluegrass players.
  • SUPERIOR PERFORMANCE: Best for rigorous practice and performance, our acoustic guitar strings can be used for fingerpicking and flat picking. If you have finger fatigue after playing or wish bending notes was easier, try a lighter string gauge.
  • VERSATILE STRINGS: String gauge is an important part of getting the best sound out of your guitar. We recommend using only our extra-light through medium-gauge strings on our guitars. Medium-gauge strings deliver more volume and are perfect for larger-bodied guitars.

Description

Martin Authentic Acoustic Strings provide unrivaled quality, craftsmanship, and tone for your acoustic guitar. Designed to produce a true, consistent tone, these bluegrass-gauge strings provide excellent tuning stability and playability so your guitar can thrive during your rigorous practice and performance schedule. Made from 80/20 bronze, these strings feature Martin's highest-quality wrap wire for enhanced longevity and durability. They are naturally corrosion resistant, so they will hold up after hours and hours of playing. This total pack of professional-grade guitar strings will last through long jam sessions, late-night campfire songs, and plenty of picking. To make these strings extra-durable and stable, we start with our highest- tensile-strength core wire and then tin-plate it on all 6 strings for added corrosion resistance. When the core is coupled with our highest-quality wrap wire, you get a consistent tone that you can count on song after song. Designed to bring out your guitar's true tone, these bronze guitar strings can be used for finger-style blues, rock, Americana, country, bluegrass, ragtime, and many more styles. With this pack, you'll receive 6 bluegrass-gauge guitar strings. The low E string measures 0.056", the A string measures 0.045", the D string measures 0.035", the G string measures 0.025", the B string measures 0.016", and the high E string measures 0.012". This total set of bluegrass- gauge strings features a tension of 193.0, and they make it easy to get a rich, bright tone out of your guitar. Martin Guitar has been producing high- quality, musician-choice guitars and guitar accessories since 1833. The Martin Authentic Acoustic Bluegrass-Gauge Guitar Strings are the real deal—not an imitation. Discover your guitar's true voice with this professional-grade guitar string pack.

spent a lot of time fretting about this review...
Style: Single Size: Bluegrass, 12-56
I have used Martin Bluegrass strings for many years. They have nice brightness in the trebles, and warm bass notes. They last about like most strings. Solid quality strings from a company well known for their products. I will probably continue to use them. After playing guitar for years, I thought it would be easy to learn the piano. But it's not an easy instrument to pick up... ... show more
